The small partners who are familiar with digital products know that the mobile phone development in recent years is very rapid. In just two or three years, the CPU has grown from a single core to eight cores, and even a chip brand has directly reached 10 cores. The lens is also from single shot to the current mainstream dual camera and Yuba four. However, careful friends may notice that even the news such as "a manufacturer has developed a graphene super battery..." has been spreading a lot of years ago, and the battery has not been much developed.
The stagnant battery industry has driven the rapid development of the fast charge industry. In just a few years, the fast charge has gone from the original 10w to the current 40w super fast charge. The development of fast charge is like a high-speed rail that expresses expressly and directly. However, although they are all fast-filled, the differences between platforms are also very large. Today, Assen will take everyone to see the fast charge of different platforms, what is the difference.
Fast charging, as the name implies, is fast charging. It refers to adjusting the input voltage of the voltage and current of the mobile phone through technical means, thereby shortening the charging time of the mobile phone. At present, the mainstream fast charging mode on the market has three modes of high voltage constant current, low voltage high current, high voltage and high current. For each of these three fast-charge modes, each vendor has a different choice, resulting in multiple fast-charge protocols. Among the more popular ones are Qualcomm's QC3.0, MediaTek's PE protocol, oppo, vivo flash charging, and Huawei's fast charging technology.
Although the fast charging standard of the market circulation can be roughly divided into three major factions: “high voltage, low power, low voltage and high current, and synchronous supply of voltage and current”, there are differences in compatibility between various subdivision protocols, especially various non- The “original certification” charger charging line can't normally open the fast charging flow limit, which makes it difficult for us to find out which mobile phone manufacturer will launch a product that also serves multiple fast charging protocols. However, this pattern is actually being broken by Wanshuntong power bank suppliers.
Shenzhen Wanshuntong Technology Co., Ltd. has relevant application solutions, which have largely solved two major problems in the current market: 1. Wide range of adaptable fast charge standards, and support for such as SuperCharge, PD, VOVC, etc. The latest high-power protocol standards; 2, with support for different protocols, these solutions can also be applied to different segments of the charging treasure, charger and car charging.
WST's so-called unwillingness to engage in fast-filled products is more important because the cost of ICs supporting fast charging is too high, resulting in expensive or even unsatisfactory product prices. But after the latest round of solution iterations, the fast charge is too high to say that it is not a problem.
WST will release new products in 2019. The highlight of this powerbank is not only the discount, it can support up to 45W output (under the PD standard). In contrast, chargers that currently support PD fast charging generally support fewer protocols, not to mention Apple's support for PD fast charging USB-C chargers.
